HAND PROPELLING MECHANISM FOR BOATS.

SPECIFICATION forming part of Letters Patent No. 643,464, dated February13, 1900.

Application filed September 21, 1898. Serial No. 691,493. (No model.)

To all whmn it may concern:

Be it known that I, FRANK BURNS, a citizen of the United States,residing in Philadelphia,

boat by simply mounting the propelling attachment in the usual socketsfor the oarlocks, as fully described hereinafter.

In the accompanying drawings, Figure 1 is a side view of a boat,illustrating my invention. Fig. 2 is an enlarged end view of a portionof the propelling mechanism. Fig. 3 is a section on the line 3 3, Fig.2. Fig. 4 is a perspective View of the rear guide for thepropeller-shaft; and Fig. 5 is a plan view of a boat, showing myimproved propelling mechanism arranged on both sides of the same.

A isa boat having two sockets a a on each side and of the ordinary formadapted to receive oar-locks. insert in each forward socket the pin 12of the driving-head B. 7 On the driving-head is a standard I), havingthe bearings 19 for a shaft 0, and on one end of. this shaft is a crank0, having a handle 0, and on the opposite end of the shaft is a bevelgear-Wheel 0 which meshes with the bevel-pinion d on the propeller-shaftD. This propeller-shaft is adapted to bearings e e, the bearing e beingloosely mounted on an extension of the shaft 0, while the bearing 6' ismounted on a spring-support e pivoted to the base of the driving-head B.

In order to protect the person propelling the boat, I inclose thegear-wheel c in a circular case J of any suitable design.

In order to hold the propeller-shaft D lat erally, I mount in the rearoar-lock socket the pin '5 of a guide I, having a slot i, through whichthe propeller-shaft D passes. This guide, with the bearings e 6, tendsto retain the propellers in position laterally.

On the lower end of the shaft D is a propeller D of any suitableconstruction, and inclosing the propeller is a cage d.

If the boat should be propelled intoshallow water, the propeller wouldnot dig into the river-bottom, but the cage would simply rest on thebottom and the lower end of the propeller-shaft would beraised, as thespring 6 I remove the oar-locks and allows of vertical movement of theshaft, and the rear bearing being slotted allows freedom of motion in avertical direction.

There is one of the propelling devices at each side of the boat, so thata person sitting in the forward thwart can'propel the boat by the twopropellers mounted on each side thereof.

The propelling mechanism can be readily removed from the boat andapplied thereto without having to adjust the parts.

I claim as my invention-- 1. The combination of a boat having sockets atthe gunwale, with a detachable propelling mechanism having pins adaptedto the sockets at one side of the boat, said propel ling mechanismconsisting of a driving-head, a shaft and a propeller, substantially asset forth.

l 2. The combination of a boat having sockets at the gunwales on eachside thereof, with two independent propelling mechanisms,each mechanismconsisting of a driving-head, a shaft, a propeller and a rear guide,said driving-heads and guides having pins adapted to the sockets on thegunwales, substantially as set forth.

3. The combination in propelling mechanism for boats, of a frame adaptedto be secured to the gunwale of the boat, a shaft in said frame, a crankon said shaft, a bevelwheel also on the shaft, a propeller-shaft havingat one end a bevel-wheel meshing with the bevel-wheel on thecrank-shaftand having at the other end a propeller, said shaft having apivot-bearing and a spring-supported bearing, substantially asdescribed.

a. The combination of a boat having sockets in the gunwale thereof, adriving-head adapted to the forward socket,-said driving head consistingof a frame having a crankshaft, a propeller-shaft adapted to bearings onthe frame and having a bevel-pinion meshing with the bevel-wheel, aslotted guide adapted to a socket and through which the propeller-shaftextends, substantially as described.

5. The combination in driving mechanism for a boat, of an inclinedpropeller-shaft, a propeller at the lower end of the shaft, a cageinclosing said propeller, and a bevel-pinion on the opposite end of theshaft, a frame adapted to be secured to the gunwale 0f the boat, acrank-shaft on said frame, a bevel- In testimony whereof I have signedmy name to this speeificatian in the presence of wheel on thecrank-shaft meshing with the two subscribing witnesses. bevel-wheel onthe propeller-shaft, a slotted guide for the propeller-shaft, and aspringsupported bearing for the upper end of the propeller-shaft,substantially as described.
